Definitions

  • the sterilant vapor is mixed with a carrier gas that carries the sterilant vapor into, through, and out of the chamber.
  • the chamber is generally near atmospheric pressure, but may be at either a positive or negative pressure.
  • a closed-loop, flow- hrough vapor phase decontamination system is provided.
  • a sealable chamber has an inlet port and an outlet port.
  • a closed-loop fluidic circuit has a first end fluidicly connected with the chamber inlet port and a second end fluidicly connected with the chamber outlet port.
  • the fluidic circuit provides a path for recirculating a carrier gas into, through, and out of the chamber.
  • a means circulates the gas through the closed-loop fluidic circuit.
  • a vaporizer is fluidicly connected to the fluidic circuit adjacent to the inlet port for delivering a decontaminant vapor into the recirculating carrier gas.
  • a monitor monitors for at least two of temperature, relative humidity, and decontaminant vapor concentration in the chamber.
  • the system includes an additional chamber pressure fine-tuning unit 70, fluidly connected to the conduit circuit, that may be used to fine-tune the pressure in the flow path by adding minute quantities of atmospheric air or removing minute quantities of the carrier gas in the conduit circuit.
  • This unit is preferably employed when carrier gas flows having high flow rates are used and the unit may be used to fine-tune the pressure in the enclosure without changing the speed of the blowers of the blowing unit.
  • the chamber pressure fine-tuning unit 70 preferably comprises an air line 72, positioned upstream of blower 22a, fluidly connecting the conduit circuit to atmospheric air via two-way valve 74 and three-way valve 76.
  • Three-way valve 76 is fluidly connected to a pump 78.
  • the adding and removing processes may be continued in a see-saw fashion until the point of desired enclosure pressure is reached, at which time the pressure fine-tuning unit is deactivated.
  • the activation or deactivation of the unit is processor controlled based on feedback from at least pressure sensor 54.
  • the system includes a processing unit
  • Example 1 The chamber temperature is 35°C, relative humidity is 20%, and sterilant vapor concentration is 2.27 mg/1.
  • Reference to TABLE 1 or another available dewpoint concentration chart shows that the sterilant dewpoint concentration is 2.810 mg/1. The percent saturation is therefore 80%.
  • variable valve is repositioned to bypass a larger fraction of air flow around the air dryer.
  • the background humidity in the returning air stream at dewpoint conditions at 40°C for a 3.081 mg/1 hydrogen peroxide vapor concentration according to TABLE 1 is 30%.
